I don't think I would part with my Tempest; it was in a sorry state when I bought it, and have 'rescued' it with a good fettle and re-lube, polished the scratches out of the the glossy areas, and fitted some airgunner walnut grips. I am part way though fashioning a wooden box that will have green baize inside and maybe brass corners on the outside.

My other keeper is a Zastava GP45 that I have re-built and re-styled the grip to be like a Baikal MP35 rapid fire 22LR. It isn't very powerful, but is great fun and doesn't go into full-auto now either!
